ROOFING- MACHINE.

miiginal application filed May 5, 1913, Serial No. 765,696.

To all whom it may concern Be it known that we, HARRY CUMrnR and OWEN D.MCFARLAND, both citizens of the United States, residing at Chicago, inthe county of Cook and State of Illinois, and Mishawaka, county of St.J'oseph and State of Indiana, respectively, have invented certain newand useful Improvements in Roofing Machines, of which the following is a1 specification.

This application is a divisional application of an original applicationfiled May 5, 1913, Serial #765696.

Our invention relates to that class of ma terial known as roofing paperor felt in which a strip of suitable material is coated with tar,asphaltuin or other suitable waterproofing material and finely dividedor gran-.

ular slate, soap stone or sand is more or less imbedded in the waterproofing material and thereby attached to the exposed side of thefinished sheet. 1

The object of our invention herein described is to produce a novel andimproved mechanism for laying the granular material on in patterns usingmaterial of yarious colors or other physical characteristics; to

produce 'a more ornamental and thus a more desirable roof.

To this end, our invention consists in the novel construction,arrangement and combination of parts herein shown and described and moreparticularly pointed out in the claims.

In the accompanying drawings:

Fig. 1 is a side elevation of a machine for carrying out the process.

Fig. 2 is a plan view of the same.

Fig. 3 shows a desirable form of the finished roofing material.

In the form shown in the drawings 1-1 are rollers or other suitablemeans arrange for supporting the coated roofing material 2 preferablyarranged toreceive the material as it comes from the usual coatingmachines (not shown). A pattern belt is arranged directly above thestrip 2' as t lays on the supports 1 is supported in position by a pairof drums or rollers 3-3 so arranged so that the part of the patternadjacent the roofing material is just out of contact Wlth Divided and.this application fifled April 1,

the water-proofing material. The pattern belt 7 is provided withapertures 8-8 through its surface of any desired form or size adapted toaccurately correspond with some 'figure or part of a figure which it isdesired to show in a design upon the surface of the finished material;for example, in the form shown a series of square or rectangularopenings 8-8 are provided of substantially uniform size and theirdiagonals in line. The several openings, however, are separated by aspace 9 sufficient to permit an opening of substantially the same sizeto be positioned between their adjacent corners.

second pattern belt 10 is provided having a similar series of openings 8is mounted upon suitable drums or rollers H and arranged to co-operatewith the pattern belt 7 so that when the roofing material 2 is movedsynchronously with the belts 7 and 10 an impression of the openings ofthe two pattern belts will show a series of squares or rectangles 13connected at their corners as shown in Fig. 3. Obviously where thecompleted design is such that the squares or other figures aresufficiently separated from each' other to permit all the figures of onecolor or kind to be cut through the surface of a single patternbut-"without unduly weakening it, a similar pattern belt may be employedandproduce substantially the same result. Any suitable means may beprovided to direct a suitable granular material through the openings inthe pattern belts to the roofing material beneath them. In the formshown a hopper 11 is positioned between the drums 33 with a suitablefeeding mechanism 12 of any desired form adapted to discharge apredetermined amount of the material in the hopper at a substantiallyuniform rate over the entire surface d of the side of the belt 7adjacent the roofing material 2. A brush or scraper 14 is provided todirect the granular material from the feeder to the belt and prevent itsbeing carried by the belt beyond the scraper where it might interferewith the operation of the belt or become dusted over those portions ofthe material intended to be protected by the solid portions of thepattern. A hopper 15 with feeder 16 and scraper 17 is provided belts 7and 10, while the remaining one-half also in the form of squares will beentirely free from the same. The'drums 5-5 6.6' are provided withpattern belts 18 and 19 respectively and with hoppers 20 and 21 andfeeders 22 and 23 and with scrapers 24 and 25 adapted to operate in allrespects substantially the same asthe corresponding,

parts hereinbefore described. The pattern belts 18 and 19 are arranged,however, to deposit material on the bare or unoccupied portions of theroofing material, thus form: ing a uniform coating over the-entiresurface of the roofing material at the same time by providing granularmaterial to the hoppers 11 and 15 of one color and to the hoppers 20 and21 of a sharply contrasting color, a roofing material will be providedhaving its entire surface covered uniformly with any desired number orkinds of railular material arranged in. any desire design, the severalparts of which may be formed of material of any desired color orphysical characteristics to produce the effect sought. A roller 26 ispreferably provided beyond the several pattern belts, to press thegranular material firmly upon the coated surface of the roofing material2to imbed the granules into and securely attach them to the surface ofthe water roof coating of the material. Any sultable means may beprovided for operating the several pattern beltsl In the form shown asprocket wheel 30 is rigidly attached to each of the several drums. Anda sprocket chain 31 or other convenient means is provided connecting theseveral sprocket wheels and arranged to accurately maintain the timingof the several drums and the pattern belts mounted thereon, themechanism is so constructed and arranged that the several belts moveabsolutely synchronously with the roofing material 2 thus accuratelymaintaining pattern in position upon the roofing material and insuringavclear, sharp outline for the design.

We claim as our'invention:

1. A device of the kind-described .comprising means for feeding a sheetof roofing coated with an adhesive waterproofing material, of means forfeeding granular material of a given size and color to predeterminedareas of said roofing-determined by endless perforated pattermbands andmeans in advance of the first named means for feeding granular materialof the'same size but different color to the Other areas, of saidroofing.

2. A device of the kind described com-' prising means for feeding asheet of roofing coated with an adhesive waterproofing material, incombination with endless bands having perforated patterns and mountedabove and in close proximity with said sheet,

means for feeding granular material of a predetermined size and colorthrough the pattern of one band and different colored material throughanother pattern band.

3. A device of the kind described comprising means for feeding a sheetof'roofing coated with an adhesive waterproofing material in combinationwith endless pattern belts having perforated patterns therein mountedadjacent the sheet and covering diflerent areas thereof, means forfeeding granular material of varied colors or sizes through thedifferent patterns onto the sheet. 4.
